Grounds for Divorce

Oregon is a no-fault divorce state. You do not need to prove wrongdoing by either spouse. The only ground required is that the marriage is irretrievably broken. This is governed by ORS §107.025.

No-fault filing simplifies the process and typically reduces litigation costs significantly.

Property Division

Oregon is an equitable distribution state. This means courts divide marital property in a manner that is fair and equitable, but not necessarily equal. Judges consider factors including length of marriage, each spouse's earning capacity, contributions to marital assets, and the economic circumstances of each party.

The median uncontested divorce in Oregon costs approximately $10,000. Contested cases with significant property disputes average $42,000.

Child Custody

Oregon courts determine custody based on the best interest of the child standard. Courts consider the child’s relationship with each parent, each parent’s ability to provide a stable environment, the child’s adjustment to home and school, and any history of domestic violence or substance abuse.

Oregon uses the Income Shares model. Both parents' incomes are combined, and a state guideline table determines the total support obligation. Each parent's share is proportional to their percentage of the combined income.

Alimony & Spousal Support

Spousal support in Oregon is determined by considering the length of the marriage, each spouse’s income and earning capacity, the standard of living established during the marriage, and each spouse’s contributions (including homemaking). Courts may award temporary, rehabilitative, durational, or permanent alimony depending on the circumstances.

Under ORS §107.025, the court has broad discretion in setting the amount and duration of spousal support. Longer marriages (typically 15+ years) are more likely to result in longer-term or permanent alimony awards.
